The 100 Most Expensive Keywords on Google [Infographic]

Google has many different sources of revenue, but one of their most noticeable is the ads that appear next to search results for specific keywords. How much that keyword costs depends, in part, on how often people search for it -- the more people search for a certain keyword, the more expensive it is.

If you've ever wondered what the most expensive keywords on Google are, then look no further than the infographic below from WebpageFX. With the help of the folks at SEMrush, WebpageFX figured out which keywords have the highest cost-per-click in Google AdWords.

They found, for example, that 58% of keywords are location-sensitive -- like "Austin TX auto insurance" as opposed to just "auto insurance." They also found that a whopping 78% of the most expensive keywords relate to law firms and legal counsel, while only 1% relate to business services.
